Getting an array in a django function
I send data from JS via JSON var pricesum = sumprice; var date = expirationdates; var price = prices; $.ajax({ type: "POST", url: "print", data: { 'pricesum': pricesum, 'date': date,'price': price, }, They have the following form expirationdate = request.POST.get('date', False); price =request.POST.get('price', False); print(expirationdate) print(price) Next, I get them in the django function, but I always get false. How do I get them correctly so that they are all in the array? -

What is the correct way of creating APIs which contain multiple tasks?
Any help would be appreciated. I am creating a small application which has facebook type feature of sending friend requests and adding friends. So I wanted to know the correct way to implement this keeping REST architecture in mind. When a person accepts a friend request, I need to perform 2 functions, firstly add that person as a friend in my model Friend and delete the friend request from the model FriendRequest. So as of now I have created 2 APIs, one to add Friend through a POST request and another to delete Friend Request through a DELETE request. Issue with this method is that, in the frontend we will have to make 2 synchronous requests and if the network is lost between these requests it will obviously create problems. Thank you in advance. -

How can I have two POST requests in the same view without getting MultiValueDictKeyError?
my view originally worked as a search engine (in which the POST request returns the search results) but I added a function so that the user can 'favorite' any item that's returned so that it'll be added to their profile. However, since I have two different post requests, the second request (which is the one to favorite the item) returns MultiValueDictKeyError since it's still referencing the first post request. How can I make my view take both different requests? This is the view code (def anime is the one not working): def search(request): animes = [] if request.method == 'POST': animes_url = 'https://api.jikan.moe/v3/search/anime?q={}&limit=6&page=1' search_params = { 'animes' : 'title', 'q' : request.POST['search'] } r = requests.get(animes_url, params=search_params) results = r.json() results = results['results'] if len(results): for result in results: animes_data = { 'Id' : result["mal_id"], 'Title' : result["title"], 'Episodes' : result["episodes"], 'Image' : result["image_url"] } animes.append(animes_data) else: message = print("No results found") for item in animes: print(item) context = { 'animes' : animes } return render(request,'search.html', context) def anime(request): if request.method == "POST": anime_id = request.POST.get("anime_id") anime = Anime.objects.get(id = anime_id) request.user.profile.animes.add(anime) messages.success(request,(f'{anime} added to wishlist.')) return redirect ('/search') animes = Anime.objects.all() return render(request = request, template_name="search.html") This is the … -
Prevent Inline Showing When Adding a New Object
I have two one-to-one related models in Django. Simplified version as follows: class User(models.Model): name = models.CharField(max_length=40) class Profile(models.Model): age = models.IntegerField() user = models.OneToOneField(User, on_delete=models.CASCADE) I have used signals to automatically create a profile automatically when a new user is created. I have also created a ProfileInline and included it in my UserAdmin as follows: class ProfileInline(admin.TabularInline): model = Profile can_delete = False class UserAdmin(admin.ModelAdmin): list_display = ('name',) inlines = [ProfileInline,] The problem I am facing is that when a new User is being created in the admin module, and the person creating the new user also populates the field for the inline on the same page, an error is generated while saving because both the signals module and the admin are trying to create a new Profile. Is there any way to prevent the ProfileInline from showing in the UserAdmin when adding a new User? Thanks. -

Back-end vs front-ent django vs react and tensorflow.js
I am not completely sure whats the difference between front-end and back-end Is, some rough definitions you find around are that front-end is just the user interface, and the back-end is the functionality. But in principle, you can also implement the functionality in javascript, and part of the UI can also be the functionality of the website. For example if you have a calculator web app, the rendering can go along side with the functionality (you can hard code the calculations and render them). Can you clarify this and maybe illustrate it with a clear example? Does front-end mean that it runs completely on the browser and back-end runs on the server? Can a python app run completely on the browser? if not, why? for example if you just render the views with Django for a static web app, would this run locally on the browser? or it would run on the server? why? What is the advantage of running tensorflow conpletely on the browser with tensorflow.js? Isn't it better to just use python and tensorflow to run a machine learning model? Meaning that you could build the whole web app with Django or flask. Why do companies use Django … -
